A137
Description:
A137 is a basic skin, Cr19Ni10Nb stainless steel electrode with low carbon and Nb stabilizer, has excellent resistance to intergranular corrosion. Using DC reverse, can be all-position welding.
use:
Used for welding important corrosion-resistant Ti-containing 06Cr18Ni11Ti stainless steel.
